20130322253 | SYSTEM AND METHOD FOR INTER-DOMAIN RSVP-TE LSP LOAD BALANCING - A system, method and apparatus for causing network routers such as Area Border Routers (ABRs) to use a preferred tie-breaking mechanism to select one path in the event of an ERO expansion operation resulting in multiple equal cost paths. | 12-05-2013 |
20130322254 | SYSTEM AND METHOD FOR MANAGING MPLS-TE OVERLOAD - A system, method and apparatus for detecting MPLS-TE overload conditions and informing a IGP routing protocol, wherein the IGP routing protocol communicates the overload condition to the nodes in the MPLS TE routing domain by inserting new flag or bit value in an OSPF Router Information Capability TLV or an IS-IS Router Capability TLV. | 12-05-2013 |
20140029413 | SYSTEM AND METHOD USING RSVP HELLO SUPPRESSION FOR GRACEFUL RESTART CAPABLE NEIGHBORS - A system, method and apparatus adapting one or more routers or nodes in a network to operate in a first mode to exchange hello messages with neighboring nodes to indicate thereby active or live status, and to operate in a second mode to avoid the use of hello messages by opportunistically relying upon service or management protocols to convey active or live status. | 01-30-2014 |
20140029418 | SYSTEM AND METHOD FOR SWITCHING TRAFFIC FROM SUB-OPTIMAL PRIMARY P2MP TO STANDBY P2MP - A system, method and apparatus in which RSVP path messages are modified to indicate that a failed source-to-leaf (S2L) sub-LSP or path has switched (or is switching) to a bypass S2L sub-LSP or path via a local-protection mechanism. | 01-30-2014 |
20140029419 | SYSTEM, METHOD AND APPARATUS PROVIDING MVPN FAST FAILOVER - A system, method and apparatus of failover indication of a Multicast Virtual Private Networking (MVPN) P-Tunnel at a leaf provider equipment (PE) router. Border Gateway Protocol (BGP) Bidirectional Forwarding Detection (BFD) attributes may be adapted to associate a BFD discriminator with a P-Tunnel terminated at the Leaf PE router such that BFD session status may be used to indicate a tunnel failure condition. | 01-30-2014 |
20140029438 | SYSTEM, METHOD AND APPARATUS CONFORMING PATH COST CRITERIA ACROSS MULTIPLE ABRs - A system, method and apparatus for adapting the operation of Area Border Routers (ABRs) in a network such that all ABRs use a common tie-breaking mechanism or process to select a particular path where equal cost multiple paths (ECMP) exist. | 01-30-2014 |
20140269747 | SYSTEM AND METHOD FOR REFLECTING FEC ROUTE INFORMATION - Systems, methods, architectures and/or apparatus for reflecting information between provider equipment (PE) nodes associated with a Virtual Private LAN Service (VPLS) via a network element adapted to operate as a Forwarding Equivalence Class (FEC) Reflector (FR) node | 09-18-2014 |
20150256452 | SYSTEM AND METHOD FOR REFLECTING FEC ROUTE INFORMATION - Systems, methods, architectures and/or apparatus for reflecting information between provider equipment (PE) nodes associated with a Virtual Private LAN Service (VPLS) via a network element adapted to operate as a Forwarding Equivalence Class (FEC) Reflector (FR) node | 09-10-2015 |
